One should not try to offer As-Salat (the prayers) just before sunset
حَدَّثَنَا مُحَمَّدُ بْنُ أَبَانَ، قَالَ حَدَّثَنَا غُنْدَرٌ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي التَّيَّاحِ، قَالَ سَمِعْتُ حُمْرَانَ بْنَ أَبَانَ، يُحَدِّثُ عَنْ مُعَاوِيَةَ، قَالَ إِنَّكُمْ لَتُصَلُّونَ صَلاَةً، لَقَدْ صَحِبْنَا رَسُولَ اللَّهِ صلى الله عليه وسلم فَمَا رَأَيْنَاهُ يُصَلِّيهَا، وَلَقَدْ نَهَى عَنْهُمَا، يَعْنِي الرَّكْعَتَيْنِ بَعْدَ الْعَصْرِ.
Narrated Muawiya: You offer a prayer which I did not see being offered by Allah's Messenger (ﷺ) when we were in his company and he certainly had forbidden it (i.e. two rak`at after the `Asr prayer).
